It will also be clear that if theauxiliaryindicators 29 be so arranged in chain 31 as to alternatelyraise and lower lever 26 which is fast to lever 22 and the other end toframe 6. The auxiliar pattern indicators 29 are mounted on the bars ofthe auxiliarypattern chain 31, carried b barrel 32 on shaft 5 2, andbarrel 32 is connected with astar-wheel 33, which is engaged by a pin 34on arm 35, projecting from hub 36, which is mounted on sleeve 8, and hub36 is connected to sleeve 8 by a key 37, which projects into keyway 13IO in said sleeve, so that hub 36 is, like hub 11, free to movelengthwise of sleeve 8, but turns with it.

Hub 36 is formed with an annular groove 38, which is occupied by a yoke39, and yoke t 5 39 is fast to an endwise-m ovable rod 40,1nounted inframe 6, and rod 40has fast to itablock 41, in which is a socket 42,engaged by one arm of a lever 43, pivoted at 44 to bracket 24. The otherarm of lever 43 is pivotally conzo nected to the lower end of a link 45,which is pivotally connected at its upper end to a lever 46, fulcrumedupon a bar 47, which is also the fulcrum of the levers (not shown) foroperating the box-shifting mechanism. Lever 2 5 46 is acted upon by theends of certain of the bars of the main box-pattern indicator-chain 48,carried by the barrel 49, which is connected with star-wheel 16 bysleeve 50. the loom, and this condition is required par- 5 Lever 46 ismoved in one direction by the ticularly when twofaced goods are being bealternately moved into operative position 75 of two of. the bars ofchain 48 will be alternately placed in operative position and those twobars of thechain will suffice for any number of successive picks of theloom when weav- 8o ing pick-and-pick.

When the pattern being woven calls for the repeated alternation of morethan two threadsthe indicators 29 are so arranged in 85 in operativeposition each for two successive picks of the loom, so that chain 48will be moved forward two steps in succession and backward two steps insuccession.

On sleeve 8 is loosely mounted a hub 54,

from which projects an arm 55, which carries a pin 56, and hub 54 isintegral with a gear 57, which engages a gear 58, fast on shaft 3,

2. In a pattern mechanism for looms provided with a star-wheel andpin-wheel actu- 1 o ating means, a horizontal pin-wheel shaft, alongitudinally-movable pin-wheel thereon rotatable in one direction, anda second longitudinally-movable pin wheel thereon rotapositions to itsother position throws one arm 14 or 55 into operative position and theother arm out of operative position.

It will now be clear that so long as lever 26 is held in its uppermostposition by auxiliary chain 48 will be moved forward in one directionstep by step and arm 55 will occupy its inoperative position, and thatso long as there are no auxiliary indicators 29 under lever 26 and thelatter occupies its lowermost positable-in the opposite direction, amain-pattern cylindershaft parallel with said pinwheel shaft, astar-wheel fast thereon, operated by one pin-wheel when in operativeposition, to rotate said main-pattern shaft in one direction, andoperated by the other pinwheel when in operative position, to rotatesaid main-pattern shaft in the opposite direction, substantially asshown and described.

3. In the pattern mechanism of a loom, a main-pattern surface,and meansto move said pattern-surface either forward or backward, anauxiliary-pattern surface, means under the control of the main-patternsurface, in either its forward or backward movement, to move saidauxiliary surface, or leave it at rest, and means under the control ofsaid auxiliary surface, to move said main surface either forward orbackward, substantially as shown and described.

4. In the pattern mechanism of a loom, having a star-wheel and pinwheelactuating mechanism, the combination with the starwheel of themain-pattern surface cylinder, of two hubs rotating in oppositedirections, and each carrying an engaging pin, and means under thecontrol of an auxiliary-pattern surface to move said hubslongitudinally, to disengage one and engage the other of the two pinswith the said star wheel, whereby the patternsurface may be movedforward or backward, as one or the other of the pins may be inengagement with the said star wheel, substantially as shown anddescribed.

5. In the pattern mechanism of a loom, having a star-wheel and pin-wheelactuating mechanism for the main and auxiliary pattern indicatingmechanism, a pin-wheel shaft carrying a pin-wheel hub movablelongitudinally, to move the main-pattern chain starwheel in onedirection, and a second hub movable longitudinally, to move saidstarwheel in the opposite direction, and an endwise-movable rod carryinga yoke engaged with one of said hubs, and a second yoke engaged withsaid second hub, and intermediate connections between saidendwise-movable rod and said auxiliary-pattern mechanism, to placeeither of said hubs in operative position to move said main-patternstar-wheel in either direction, substantially as shown and described.

6. In a loom having a star-wheel and pinwheel actuating mechanism, amain and auxiliary pattern indicating mechanism, a pinwheel shaft forcarrying a pin-wheel hub movable longitudinally,to move themain-patternchain star-wheel in one direction, and a second hub movablelongitudinally, to move said star-wheel in the opposite direction, anendwise-movable rod carrying a yoke engaged with one of said hubs, and asecond yoke engaged with said second hub, and intermediate connectionsbetween said endwise-movable rod and said auxiliary-pattern mechanism toplace either of said hubs in operative position to move saidmain-pattern star-wheel in either direction, and a third hub on saidpin-wheel shaft, movable longitudinally, to move the multiplier-patternstar-wheel, a second endwise-movalo'le rod carrying a third yoke engagedwith the third hub, and intermediate connections between saidendwise-movable rod and said main-pattern mechanism, to place said thirdhub into or out of operative position with said multiplier starwheel, tomove or leave it at rest, substantially as shown and described.

7. In a loom, the combination of a mainbox pattern-indicator chain foroperating the box-shifting mechanism, means for actuating said mainchain in one direction, separate means for actuating said main chain inthe opposite direction, automatic mechanism for controlling both of saidactuating means for effecting an automatic reverse of the main chain, anauxiliary-pattern indicator-chain, and an operative connection betweenthe main-box chain and the auxiliary chain, said operative connectionbeing controllable from an element of the main chain and comprisingmeans for being thrown in and out of operative relation to the auxiliarychain for putting the motion of the latter in and out of play.
